To all whom it may concern-:'

Be it known that I, ORRIN B. PECK, a citizen of the UnitedStates,'rcsiding at Chicago, Illinois, have invented a newand usefulImprovement in Apparatus for Centrifugally Treating Molten Material, ofwhich the following is a specification.

"he object of this invention is to provide convenient means fordeveloping and apply in g the operating-power and for adjusting thevarious parts of the apparatus relatively to each other; and theinvention consists in the features and combinations hereinafterdescribed and claimed.

In the drawings, Figure 1 is a side elevation, partly in section, of theentire machine; Fig. 2, a plan view of the apparatus shown in Fig. 1;Fig. 3, a plan view of the bed and engine plates and adjustingmechanism; Fig. at, a sfide elevation of an adjustable guide-pulley;Fig. 5,a side elevatiompartly in section, taken at right angles to Fig.a; Fig. (3, an end elevation of a portion of Fig. 1, and Fig. 7 a detailview of the adjusting mechanism shown in Fig. l.

V is the receiving-vessel; B, the curb; C, the shaft for supporting androtating the vessel; D D, journal-boxes for supporting and maintaing thevertical position of the shaft; E, a driving-pulley rigidly attached tothe shaft C; F, the engine-shaft driven by the engine G; II,adriving-wheel mounted on the shaft F; I, a driving-belt passing aroundthe wheel II and pulley I J, an adjustable guide-,

pulley; K, a bed plate or frame on which the parts are assembled; K, anengine-plate for supporting the engine and adj ustably attached to thebed-plate; L, a hand-wheel; and L, a screw-shaft, by means of which theengine-plate is moved back and forth.

The invention consists, essentially, of a centrifugalmachine having areceiving-vessel, a curb surrounding the same, a shaft provided withsuitable bearings for support-- ing and revolving the receiving-vessel,suitable mechanism for economically and effectively developing andapplying the motive power for operating such machine, and suitable meansfor adjusting the various parts relatively to each other.

The bed plate or frame K is constructed of suitable length and breadthto accommodate all parts of the apparatus, as hereinafter set forth. Iprefer to have a portion of this bed plate somewhat raised above thegeneral level of the plate, as shown at the right-hand end of Fig. 1,and upon this raised portion I place the centrifugal machine, which, asstated, has a revolving receiving-vessel, a curb surrounding the same,and a shaft provided with suitable bearings for supporting and revolvingthe vessel, such shaft being provided with a suitable driving-pulley,the details of which will be apparent from an inspection of thedrawings, and require no further description.

I next construct the engine-plate K. This plate should be of suitablesize to receive and support the various parts of the engine, ashereinafter described. It is mounted upon the bed-plate, which ispreferably provided with suitable ways or guides upon which theengine-plate rests and moves.

The engine-plate is provided, preferably, with a sufficient number ofslots 01' openings 70, through which pass bolts or screws in, at.-tached to the bed-plate. These bolts serve to assist in guiding theengine-plate and serve to hold it in any desired position.

In order to move the engine-plate back and forth, I prefer to provide ahand-wheel L, connected to the screwshaft L. This shaft is suitablyconnected to a lug or projection Z, passing through a suitable openingin the engine-plate and secured rigidly to the bedplate. The shaft alsopasses through an internal screw-threaded bearing Z, secured to theengine-plate. In the drawings I have shown this bearing as made integralwith the supporting frame-work of the engine; but it may be attached tothe engine-plate in any other suitable manner that will serve thepurpose for which it is intended. From this method of construction itwill be evident that as the han d-wheel and shaft thereto attached areturned in one direction or the other the engine-plate K will be movedback and forth upon the bedplate and held in any position desired. Toassist the screw-shaft L in holdiug the engineplate firmly in anyposition to which it is moved, screw down the bolts might be used forthe same purpose, the gist of this part of my invention consisting inmaking the engine adjustable toward and from the centrifugal machine.

To the engine plate or frame I attach, by means of any suitableframe-work, the engine G and the driving-wheel II, mounted upon theshaft F.

It has heretofore been customary in the operation of centrifugalmachines having a vertical shaft to place the driving-wheel in avertical position, giving a quarter-twist to the driving-belt. This isdifficult or impracticable, owing to the great size of the machine andthe necessarily-increased size of the belts required to drive the same,and the speed at which it is driven. I have therefore found it morepracticable and convenient to attach the driving-wheel directly to theen gine-shaft, such shaft being placed vertically, thus bringing thedriving-Wheel into a horizontal position. From this method'ofconstructing the apparatus I derive great efficiency through the directapplication of the power of the engine to the driving-wheel, and I amable to operate the machine without twisting the belt. This constructionallows a very compact arrangement of the machinery, and enables me tomake use of a short straight driving-belt of any desired size orstrength.

The belt I passes over the driving-Wheel to the pulley E upon the shaftof the centrifugal machine. The tension of sthis belt may be adjusted inwhole or in part by moving the engine-plate back and forth in the mannerabove described, the engine and driving- Wheel H partaking, of course,of the motion of the engine-plate. Although the belt may be adjusted bythis means, yet the exact amount of tension obtained thereby cannot bevery closely determined. To regulate this tension and to provide meansfor obtaining any given amount of tension, I preferably provide theadjustable guide-pulley J. This pulley is located at some suitable pointbetween the driving-wheel and the shaft of the centrifugal machine, andis so placed as to bear against the surface of the belt, and isadjustable to the frame and belt.

The supporting-frame of the guide-pulley is preferably connected to thebed-plate by means of bolts and slots, as heretofore de scribed whenspeaking of the engine-plate, and as more particularly shown in Fig. 3,so

the horizontal position, as desired.

as to allow of the adjustment thereof to and away from the belts.

In order to obtain the proper amount of pressure which may be desiredfrom time to time, I preferably provide a rope or wire fastened' to theframe-work of the pulley and running, as shown in the drawings, over asheave 7", which supports or has attached to it any desired weight. Whenit is desired to apply any certain amount of pressure to the belt, thebolts M M are loosened and a sufficient weight to create the pressuredesired is attached to the end of the 'rope j. This weight will draw thepulley against the belt, creating the desired pressure, and the bolts MH may then be tightened to hold the pulley in this position. If at anytime it be desired to increase or diminish this pressure, the bolts maybe loosened and the weights attached to the rope increased ordiminished, allowing the pulley to move toward or from the belt, and thebolts then tightened.

While I have shown and described the rope and weight as a means foradjusting the pulley, I do not intend to limit myself thereto, as othermeanssuch as a springmight be employed for this purpose. By this meansthe machine is enabled to be operated with the driving-belt at anypredetermined degree of tension.

To serve as a guide for the belt to hold it in its place, and to preventits rising or falling through stretching or any other change thatmaytake place in the belt, I preferably support the pulley .I in such amanner as to allow of its being adjusted to either side of In thedrawings I have shown the pulley supported upon trunnions N N, andcapable of being rocked one side or the other, in order to guidethebelt. WVhen it is desired to rock the pulley in either direction thebolts N are loosened, and the trunnions N N, rotated by any suitablemeans, as abar, bring the pulley into position one side or the other ofthe horizontal line in Fig. l. I have shown the pulley as rocked towardthe right; but it is evident thatif desired it might be rocked in theother direction. The pulley being rocked into the desired position, thebolts N may then be tightened to maintain the pulley in place.

I claim In combination with a centrifugal machine for the treatment ofmolten material, a bed plate or frame, an engine plate or frame, meansfor adjusting the engine to or from the machine, and an adjustablepulley to guide the belt between the engine and machine, substantiallyas described.
